inorganic zinc silicate primer (IOZ) is recommended. Surface preparation and subsequent primer application shall be carried out in accordance with the specific requirements of the relevant product data sheet. If replacement of the compatible primer or selection of other compatible primers is required, please consult PPG's field technical representative. If confirmed, surface preparation and application shall be carried out in accordance with the specific requirements of the compatible primer's product data sheet.
In addition, the coating drying and curing time before application shall also comply with the specified recoat interval requirements. The recommended typical dry film thickness for HI-TEMP Series Heat-Resistant Topcoat 1000 VS is 50–63 µm (2.0–2.5 mils).
weld spatter, smooth welds and round off sharp edges, then perform abrasive blast cleaning to SSPC SP 6, i.e. "Commercial Blast Cleaning" (equivalent to ISO-8501-1 Sa2), achieving a roughness of 25–38 µm (1.0–1.5 mils), or other surface preparation achieving the same cleaning effect is also acceptable. The surface must be clean and dry before application, with soluble salts, oil, grease and other contaminants removed. Two coats of HI-TEMP Series Heat-Resistant Topcoat 1000 VS can then be applied, each at a dry film thickness of 50–63 µm (2.0–2.5 mils), with a total cumulative thickness of 100–125 µm (4.0–5.0 mils).
soluble salts and other contaminants. After the surface is dry, apply one full coat of HI-TEMP Series Heat-Resistant Topcoat 1000 VS to a dry film thickness of 50–63 µm (2.0–2.5 mils).
with no cracking, checking or peeling found, and only small areas of local rusting (less than 10% of the total coated area), after first wiping off oil and grease, wash the entire surface with high-pressure fresh water to remove soluble salts and other contaminants. After the surface is dry, perform surface preparation, then apply one repair coat of HI-TEMP Series Heat-Resistant Primer 1027 to all areas where the existing coating has been removed and the steel is exposed, in accordance with the technical requirements of the product data sheet. After confirming the primer coat is completely dry, apply one final full coat of HI-TEMP Series Heat-Resistant Topcoat 1000 VS over the entire surface to a dry film thickness of 50–63 µm (2.0–2.5 mils).
Note: If HI-TEMP Series Heat-Resistant Topcoat 1000 VS is to be applied over other coatings, a small test area should be coated before large-area application to confirm whether adhesion meets the expected requirements.
